Abstract

Sleep deprivation is well established to cause diminution of cognitive function, including disruption of both minute-to-minute working memory and decrements in the stabilization of long-term memories. Moreover, “replay” during sleep of episodes and sequences of events that were experienced during wakefulness has been implicated in consolidation of long-term memories. However, the molecular mechanisms underlying the role of sleep in memory function are just starting to be defined. In this issue of Science Signaling, Tudor et al. identify one molecular component underlying the effects of sleep on memory function: dynamic experience-dependent regulation of protein synthesis in the hippocampus.
